is this light bleaching on the leaves?

This is an OG Kush x Purple #1
I crossed them myself. so they are my seeds. so it might not exactly be stable genetics.
its the only plant out of 4 plants that is doing this

all the other plants are fine.
but this one is doing this strange discolouration and its also growing unevenly. i think it might be a little "special".

Light is 2x 70w Samsung Quantum Boards
light is about 18" above plant

is it just Genetic or are the leaves bleaching?

Your shows characteristics of that cds virus and manganese deficiency to a lesser degree, but I really can’t be sure and am just guessing. if you recently lowered your light and that showed up I would lean more towards light bleaching, definitely stick to recommended hanging distances and keep monitoring for any possible progression. manganese deficiency’s are rare and plants usually outgrow the cds virus FYI.
